I want to say - it's EPIC! Passed it on one breath from the monastery till the end.Found only 1 secret level, and even that one by chance.

Tried to pass monastery without saves - failed to. Gun ammo I have, but the gun itself - not.Monks kill if not from second hit - from the third.Some really hit you hard."Heretic" monk sprite is overused. And you automatically expect weak attack, unlike the actual fireball.Music from "Portal" (TRACK26) is the best in the game, but the Portal itsel...some poor corridor with wooden barrack door. I thought it'll be something monumental.

Hellish levels are great! Though the setting didn't encourage you to look for secrets - so didn't look that much for them.At first I thought sceletons are endless, or endlessly resurrecting - and so you need to burn them or break them.But it went ok.

The only thing on level 21 when player is spammed from MG42 from all directions, escape is sure possible, but returning to kill them for 100% kills is very...frustrating.

Final level is really hard. Tried to play without saves - all the time got killed by the zombie with Blue Armor "Gutentags".Ending didn't please me. Sure, Zombie Hitler is cool, but his entourage...fighting in the background hellish barracks in the middle of huge pool (if you can make it)...I expected something more epic.

And the room itself where Bosses come from - it has 4 golden crosses. How you can somehow lure Hitler out, 4 "GutenTags" and smaller enemies - and yet not to kill Hitler prematurely, trying to get all the rest or lure them away, fastly run into the room and get the treasure....and all this for just 4 crosses. What the hell?

About the chaingun I can't say it's the most uberweapon. First, it has large spread over large distances and wastes tons of ammo. Secondly - against Mechas and UberMutants with weapons more serious than fists and knifes - it's not effective at all. For them - only RPG "rules".And finally, skeletons have this nasty disgusting habit of spread into 1000s of bones if gibbed.At close distance it's like shotgun effect, so against them I fought with a gun. And chaingun, if there were hordes.

Would be nice if Mechas would crash scenery, trees and specially MG42 with nazis.
